The manufacturing of carbides is a specialist branch of powder metallurgy. Work pieces made from carbides are not manufactured by means of founding but instead by means of pressing and sintering. The best known raw materials of carbides are WC, Co, Ni, TiC, TaC, NbC etc. Admittedly: This a very simplified explanation of our highly complicated manufacturing process.
We are happy to provide more details in a personal meeting. Thank you for your interest.
